We bought new Bailey S5 Pageant Bordeaux in 2005 and kept it until 2014, when we "gave up caravans and sold everything"! It was the 4 berth fixed end bed and was an excellent caravan, having a weight upgrade to 1400kg MTPLM meant we could carry 250kg payload (old style definition) and with 7m overall length it had good front settees and a nice size fixed bed. I am 6ft 4 inch. The weight upgrade required new uprated LI tyres.
It was very reliable and gave no damp problems. However at its year 2 service it had a new front panel, and a new rear panel at year 3 service. This was a manufacturing fault that affected quite a number of early S5 and caused by incorrect tightening of screws in the seals that joined the end panels to the roof. It led to cracking which could let damp in. If caught early it didn't cause a problem and the work was done under warranty.
When the S5 was introduced many experts criticised the lack of anti-condenstion panels. Bailey felt that given the S5 insulation such panels were not required. Our Dealer fitted some under warranty as we did suffer unacceptable condensation to the settee backs that I felt wasn't acceptable.
We enjoyed many holidays here and abroad in the S5 and it was a delight to tow and own.
